Cine computed tomographic (CT) examinations of the mediastinum were performed in 83 pediatric patients. Lesions imaged include neoplastic, inflammatory, and vascular abnormalities. The 50-msec scan time of cine CT provides for superb depiction of the heart and airway, minimizes motion artifact, allows examinations to be done with little or no sedation, and permits optimal opacification of all vascular structures with as little as 0.5 mL of intravenously administered contrast medium per kg of body weight. Scanning time for an examination in which images in 20 sections are obtained is approximately 10 seconds. Radiation dose is significantly lower than that in comparable CT or plain radiographic studies. Preliminary experience shows cine CT to be an excellent imaging modality for the examination of the mediastinum in children.
对83例儿科患者进行了纵隔的电影计算机断层扫描（CT）检查。成像的病变包括肿瘤性、炎症性和血管性异常。电影CT的50毫秒扫描时间能出色地显示心脏和气道，将运动伪影降至最低，允许在很少或无需镇静的情况下进行检查，并只需每千克体重静脉注射0.5毫升造影剂就能使所有血管结构达到最佳显影。获取20个层面图像的检查扫描时间约为10秒。辐射剂量明显低于同类CT或普通X线摄影研究。初步经验表明，电影CT是检查儿童纵隔的一种出色成像方式。
